What i can say about this reactor is that i tried both 7 " and 10 " water filter and the 10" dissolves the co2 much better and i think is because the water and co2 travels more and co2 has more time to dissolve in the water .
I don't have a sponge inside on the tube
Thank you so much for this post. Its the only post on how to build a ceges reactor that has a list and pictures. I bought most of what i need today, i just need a pump and hoses and im all set. Mine is built with the parts i could find so its not 100% the same. Any thoughts on the pump id need to power this? I was thinking 300gph.
